SCREENING ATTACHMENT FOR CDRK-DISK-CUTTING MACHINES.

Specification of Letters Patent.

Patented Feb. 19, 1918.

Application led Apr120, 1917. Serial No. 163,464.

To all 'whom t may concern:

Be it known that I, EMILIO ALBERTI, a citizen of the United States, and a resident of the city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Screening Attachments for Cork-Disk-Cut ting Machines, of which the following is a specication.

The present invention relates to an attachment for disk cutting machines, and more particularly to means which screens out or separates the broken disks or chips from the perfect ones. The invention pertains to a machine for producing disks from cork strips, which are to be employed in the manufacture of the well-known crown corks, or generally in the production of closures of the cap variety. n

' One of the objects of the present invention is to provide an attachment of the character described, which is simple in construction, efficient in operation, and that is actuated by one of the moving elements of the machine without the aid of a special gearing.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement, and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any 0f the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a portion of a cork disk cutting machine with the attachment constructed in accordance with the present invention mounted thereon; and Fig. 2 is a section taken on line 2-2 of Fig. 1.

Herein only as much of the cork disk cutting machine will .be described as is necessary to understand the operation of the screening attachment, the machine being more fully described in an application for U. S. Letters Patent filed by me on the 20th day of Feb. 1917, under Serial No. 149,798.

Referring now to the drawings, the numeral l0 designates the supporting frame of the machine, upon the table portion of which rests a base 11, from which rises a set of bearings 12, in which is rotatably and reciprocably mounted a tubular arbor 13. To this arbor is secured, for instance, by a clamping nut 14 a tubular cutter 15. The arbor is provided with a longitudinal groove 16 in its outer face, into which groove fits a feather key 17, attaching to the arbor a pinion 18. The pinion is held against longitudinal movement between the bearings 12, the groove and key arrangement permitting of lengthwise or reciprocating movement of the arbor, and also of rotary motion thereof. The pinion is driven from any suitable source of power by the intermediary of a driving chain (not shown). Into the arbor reaches a tubular discharge chute 19. This chute is straight and is journaled in a bearing 20, registering with the bearing set 12. Near the outer end of the chute is mounted a stop ring 21, that is adapted to abut against the hearing adjacent the same. The chute is connected with the arbor by a ring Q2 and a screw 23, the connection being such that the chute reciprocates with the arbor, but does not rotate therewith. A. ball bearing 2-1 is mounted upon the chute and abuts against the outer end of the arbor and a shoulder 25 upon the chute. This ball bearing takes up the lengthwise thrust of the arbor. The bore 26 in the cutter is conical, the diameter of the bore at its cutting edge corresponding to the diameter of the disks to be cut, and the diameter at its inner end being somewhat larger for a purpose to be de scribed. In a similar manner is the bore 27 of the chute tapered, it being smaller at its inner end, that is adjacent the cutter, than at its outer end, at which the stop ring 21 is mounted.

T he arbor and cutter are reciprocated, that is to say they are advanced toward and retracted from the work. For this purpose there is keyed to a counter-shaft 28 an eccentric 29, to the strap 30 of which is attached in any suitable manner an eccentric rod 31, to which is pivoted at 32 a lever 33, the latter being fulcrumed at 34: to the frame 10. The'upper end of this lever is fork-shaped, as shown at 35, and in engagement with pins 36, that are carried by a sleeve 37 the latter being ixedly attached to y the v chute `19L The `counter-shaft is rotatably mounted in bearings 28k on the frameml0, kand .is"-driven"from a driving fshaft'38 #by 'a suitable gearingrforinstance abevel gearY 39-up`on thedriving shaft, in mesh with a bevel gear 4L0`uponfthe countereshaft.

The cutter cooperates with a Work support 141, thej construction of which need Anot be given herein in detaihfasvit` doesinot form part of the invention. Y

The screening Ior aseparating attachment "comprises .aforaminatedsheet or plate 42,

Y :that ,=isp1ovided Iwith vertically extend-ing side'anges Spend witha 'flange All .at-'theY end-.adjacent the'chnte 19.

The `attachment @may fbesecured in any suitable manner to Y Y' -the chutefso that they disks discharged from zterfto be-reinoved'therefrom by those enb-V -;sequently being cut. The v tinishe'd product Y'movesthrough the discharge Vchute-.and 'falls Onto vtheforaminated: sheetor plate 42, Which, byrreason of itsbeing attached to the chute,
